In addition, the digit of DAI can be in the case where setting the cell less than 5 (or 5 or less) downlinks 2.In addition, the digit of DAI is also possible to 2 in the case where the first information sets (set: setting) as " 1 (or cc) ".This Outside, (set: setting) is set as " 0 (or dai) " in the first information, and dispatch the DCI format of PDSCH (that is, for downlink chain The DCI format on road) do not map to USS in the case where, the digit of DAI is also possible to 2.It (set: is set that is, being set in the first information Set) it is " 0 (or dai) ", and the DCI format (that is, the DCI format for being directed to downlink) for dispatching PDSCH maps to the feelings of CSS Under condition, the digit of DAI is also possible to 2.Here, 2 DAI are configured to 2 digit counter DCI.

Here, 2 DAI (2 DAI fields) can be used for and (can reside in) TDD.In addition, application TDD cell and In the case where applying TDD to main plot in the carrier wave polymerization of FDD, 2 DAI can be used.

That is, small to master in the case where application FDD, and/or in the cell of application TDD and the carrier wave polymerization of application FDD In the case that area applies FDD, (can be not present) 2 DAI (or DAI field) can not used.That is, setting less than 5 In the case where the cell of (or 5 or less) downlink, the digit of DAI can be 0.In addition, the first information setting (set: Setting) be " 1 (or cc) " in the case where, the digit of DAI is also possible to 0.In addition, set in the first information (set: setting) as " 0 (or dai) ", and the case where the DCI format DCI format of downlink (that is, be directed to) for dispatching PDSCH does not map to USS Under, the digit of DAI is also possible to 0.That is, setting (set: setting) as " 0 (or dai) " in the first information, and dispatch PDSCH The DCI format DCI format of downlink (that is, be directed to) map to CSS in the case where, the digit of DAI is also possible to 0.

That is, base station apparatus 3 can be sent comprising setting (set: setting) as the first of " 0 (or dai) " or " 1 (or cc) " The upper layer signal of information (codebooksizeDetermination-r13).For example, base station apparatus 3 can be sent comprising first Signal in the rrc layer of information.

For example, the terminal installation 1 for setting " 0 " as the value of the first information can at least be determined based on the value of DAI The digit (alternatively, digit of the digit of HARQ-ACK and scheduling request) of HARQ-ACK.That is, in this case, by for service The HARQ-ACK feedback that the position HARQ-ACK of cell is constituted can at least be based on DAI (the HARQ-ACK feedback consists of the HARQ-ACK bits for the serving cells based on at least DAI)。

For example, setting " 0 " as the first information to FDD (in the case where application FDD, to frame structure Class1) In the case where value, the digit of HARQ-ACK can at least be determined based on the value of DAI.In addition, to TDD (application TDD feelings Under condition, to frame structure type 2) set the value of " 0 " as the first information in the case where, the digit of HARQ-ACK at least can be with base It is determined in the value of DAI.

Here, in the sending mode (sending mode for supporting single transmission block) for setting single code word as downlink Sending mode in the case where, can to the cell use 1 HARQ-ACK.In addition, in the hair for setting two or less code words It, can be small to this in the case where sending sending mode of the mode (sending mode for supporting two or less transmission blocks) as downlink Area uses 2 HARQ-ACK.

Here, the value of counter DAI can indicate to be accompanied with associated with PDCCH for FDD and subframe n Cumulative amount (For FDD and a subframe n, the value of the of the serving cell of transmission in PDSCH counter DAI denotes the accumulative number of serving cell(s)with PDSCH transmission(s)associated with PDCCH(s)).Here, the value of counter DAI, which also may include, is accompanied with finger Show cumulative amount (the value of the counter DAI of the serving cell of the PDCCH of the SPS release of downlink denotes the accumulative number of serving cell with PDCCH indicating SPS release).That is, the value of counter DAI can indicate to be accompanied with and the serving cell of the transmission in the associated PDSCH of PDCCH The cumulative amount of the serving cell for the PDCCH that cumulative amount, and/or the SPS for being accompanied with indicating downlink link discharge.

In addition, the value of counter DAI can indicate to be accompanied with and the transmission in the associated PDSCH of PDCCH for TDD Cumulative amount (For TDD, the value of the counter DAI denotes of { serving cell and/or subframe } couple The accumulative number of { serving cell (s), and/or subframe (s) }-pair (s) with PDSCH transmission(s)associated with PDCCH(s)).Here, the value of counter DAI also may include it is attached PDCCH { serving cell and/or subframe } couples of cumulative amount (the value of of the SPS release with indicating downlink link The counter DAI denotes the accumulative number of { serving cell (s), and/or subframe(s)}-pair(s)with PDCCH indicating SPS release).That is, the value of counter DAI can be with table Show and is accompanied with and the cumulative amount of { serving cell and/or the subframe } of the transmission in the associated PDSCH of PDCCH pair, and/or subsidiary There is PDCCH { serving cell and/or subframe } pairs of cumulative amount of the SPS release of indicating downlink link.

It at least can be based on set serving cell as the terminal installation 1 of the value of the first information in addition, setting " 1 " Quantity set the digit of HARQ-ACK.That is, in this case, HARQ-ACK feedback can be by for each serving cell HARQ-ACK cascades constitute (the HARQ-ACK feedback consists of the concatenation of HARQ-ACK bits for each of the serving cells).Here, for example, upper layer can be used in base station apparatus 3 Signal sets serving cell (secondary cell).That is, in the case where setting 2 secondary cells by base station apparatus 3, it is set The quantity of serving cell can be 3 (1 main plot and 2 secondary cells).

For example, in the case where setting the value of " 1 " as the first information, the digit of HARQ-ACK at least may be used for FDD To be determined based on the sending mode of the quantity of set serving cell and the downlink set in each cell.This Outside, for TDD, in the case where setting the value of " 1 " as the first information, the digit of HARQ-ACK at least can be based on set The quantity of fixed serving cell, the downlink set in each cell sending mode and with send HARQ-ACK it is upper The quantity of the associated downlink subframe of uplink subframe determines.

Here, the determination of the digit of HARQ-ACK to be also known as to the determination (HARQ-ACK of the codebook size of HARQ-ACK codebook determination).In addition, will also set " 0 " as the first information value in the case where HARQ-ACK Process is known as being accompanied with HARQ-ACK process (the HARQ-ACK procedure with adaptive of adaptive codebook codebook).In addition, will also set " 1 " as the first information value in the case where HARQ-ACK process it is referred to as not subsidiary There is the HARQ-ACK process (HARQ-ACK procedure without adaptive codebook) of adaptive codebook.

That is, terminal installation 1 can be executed and be accompanied with adaptively in the case where setting the value of " 0 " as the first information The HARQ-ACK process of code book.In addition, terminal installation 1 can also be held in the case where setting the value of " 1 " as the first information Row is not accompanied with the HARQ-ACK process of adaptive codebook.
